Motherboard troubleshooting

We've run into a problem with a particular motherboard (Figure 1; click the images to enlarge). We can't figure out how to power it on because the pins aren't labeled. It's a Fujitsu motherboard, and we found two numbers etched onto the board, w26361 w57 x 03 and w57 z2 04 36. A Google search yielded little to nothing.

We think maybe the power pins are on this set of pins labeled FRONT (Figure 2) but we tried every pair combination and the computer still refused to start.

Help!

Update: Problem solved. We were completely wrong about the pins. They were located on a completely different part of the motherboard, though it took a few heads put together to piece the puzzle together!
